A nation which depends upon others for its new basic scientific knowledge will be slow in its industrial progress and weak in its competitive position in world trade, regardless of its mechanical skill.

After 16 months of teaching, consulting, fellowship, and special project activities on matters ranging from conservation to healthcare to international trade, Gov. Ventura appointed me to the Minnesota Court of Appeals.

All that Eddington and Millikan achieve, when they attempt their preposterous reconciliation of science and theology, is to prove that they themselves, for all their technical skill, are scientists only by trade, not by conviction. They practice science diligently and to some effect, but only in the insensate way in which Blind Tom played the piano. … they can’t get rid of a congenital incredulity. Science, to them, remains a bit strange and shocking. They are somewhat in the position of a Christian clergyman who finds himself unable to purge himself of a suspicion that Jonah, after all, probably did not swallow the whale.

Archimedes possessed so high a spirit, so profound a soul, and such treasures of highly scientific knowledge, that though these inventions [used to defend Syracuse against the Romans] had now obtained him the renown of more than human sagacity, he yet would not deign to leave behind him any commentary or writing on such subjects; but, repudiating as sordid and ignoble the whole trade of engineering, and every sort of art that lends itself to mere use and profit, he placed his whole affection and ambition in those purer speculations where there can be no reference to the vulgar needs of life; studies, the superiority of which to all others is unquestioned, and in which the only doubt can be whether the beauty and grandeur of the subjects examined, or the precision and cogency of the methods and means of proof, most deserve our admiration.

Criticism is as often a trade as a science, requiring, as it does, more health than wit, more labour than capacity, more practice than genius.

Engineering without imagination sinks to a trade.

Events in the past may be roughly divided into those which probably never happened and those which do not matter. This is what makes the trade of historian so attractive.

He who first stretched his nerves of subtile wire
Over the land and through the sea-depths still,
Thought only of the flame-winged messenger
As a dull drudge that should encircle earth
With sordid messages of Trade…

I am afraid I shall have to give up my trade; I am far too inert to keep up with organic chemistry, it is becoming too much for me, though I may boast of having contributed something to its development. The modern system of formulae is to me quite repulsive.

I trade both with the living and the dead for the enrichment of our native language.

I would trade all the advantages of humanity to be a fly on the wall when Franklin and Jefferson discussed liberty, Lenin and Trotsky revolution, Newton and Halley the shape of the universe, or when Darwin entertained Huxley and Lyell at Down.

In physical science … whatever knowledge is once gained forms a lasting fund for afterages to inherit and trade with.

Included in this ‘almost nothing,’ as a kind of geological afterthought of the last few million years, is the first development of self-conscious intelligence on this planet–an odd and unpredictable invention of a little twig on the mammalian evolutionary bush. Any definition of this uniqueness, embedded as it is in our possession of language, must involve our ability to frame the world as stories and to transmit these tales to others. If our propensity to grasps nature as story has distorted our perceptions, I shall accept this limit of mentality upon knowledge, for we receive in trade both the joys of literature and the core of our being.

Is education possibly a process of trading awareness for things of lesser worth?

It is not easy to be a pioneer—but oh, it is fascinating! I would not trade one moment, even the worst moment, for all the riches in the world.

It is the middle of the night when a glittering theatre of light suddenly appears in front of the Dhaka. Where, moments before there was only darkness, suddenly there are hundreds of columns of light. The sound of helicopters and car horns carry across to the ship on the breeze. There is the scent of rain after it has evaporated from warm streets. This is unmistakably Singapore, the small city-state at the most southern point of the Asiatic mainland. Singapore was built as a centre for world trade by the British over 250 years ago, and today, Singapore has the largest container harbour in the world. This is where the axes of world trade cross paths: from the Far East to Europe, from the Far East to Southeast Asia/the East, and from the Far East to Australia. Everything runs like clockwork here. Within five hours the Dhaka has been unloaded.

Let the artist have just enough to eat, and the tools of this trade: ask nothing of him. Materially make the life of the artist sufficiently miserable to be unattractive, and no-one will take to art save those in whom the divine daemon is absolute.

My impression about the Panama Canal is that the great revolution it is going to introduce in the trade of the world is in the trade between the east and the west coast of the United States.

Nursing has sometimes been made a trade, sometimes a profession; it will never be what it should be until it is made a religion.

Of plain, sound sense, life’s current coin is made; With that we drive the most substantial trade.

Our commercial and mercantile law was no sudden invention. It was not the work of a day, or of one set of minds… In the incipient, the early existence of this system, a single maxim obtained force, others succeeded; one rule of right formed a nucleus around which other kindred rules might cling; the necessities of trade originated customs, customs ripened into law; a few feeble decisions of courts laid the foundation for others; the wisdom and experience of each succeeding generation improved upon the wisdom and experience of generations that were past; and thus the edifice arose, perfect in its parts, beautiful in its proportions.

People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. It is impossible indeed to prevent such meetings, by any law which either could be executed, or would be consistent with liberty and justice.

Science is like society and trade, in resting at bottom upon a basis of faith. There are some things here, too, that we can not prove, otherwise there would be nothing we can prove. Science is busy with the hither-end of things, not the thither-end. It is a mistake to contrast religion and science in this respect, and to think of religion as taking everything for granted, and science as doing only clean work, and having all the loose ends gathered up and tucked in. We never reach the roots of things in science more than in religion.

The Chinese … use fossil teeth as one of their principal medicines. Some Chinese families have for centuries been in the business of “mining” fossils to supply the drug trade.

The development doctrines are doing much harm on both sides of the Atlantic, especially among intelligent mechanics, and a class of young men engaged in the subordinate departments of trade and the law. And the harm thus considerable in amount must be necessarily more than considerable in degree. For it invariably happens, that when persons in these walks become materialists, they become turbulent subjects and bad men.

The feudal model of agriculture collided, first, with environmental limits and then with a massive external shock – the Black Death. After that, there was a demographic shock: too few workers for the land, which raised their wages and made the old feudal obligation system impossible to enforce. The labour shortage also forced technological innovation. The new technologies that underpinned the rise of merchant capitalism were the ones that stimulated commerce (printing and accountancy), the creation of tradeable wealth (mining, the compass and fast ships) and productivity (mathematics and the scientific method).

The inner circle of creative mathematicians have the well-kept trade secret that in a great many cases theorems come first and axioms second.

The microbial global brain—gifted with long-range transport, data trading, genetic variants … and the ability to reinvent genomes—began its operations some 91 trillion bacterial generations before the birth of the Internet. Ancient bacteria, if they functioned like those today, had mastered the art of worldwide information exchange. … The earliest microorganisms would have used planet-sweeping currents of wind and water to carry the scraps of genetic code…

To the north [of Armenia] lies Zorzania [Georgia], near the confines of which there is a fountain of oil which discharges so great a quantity as to furnish loading for many camels. The use made of it is not for the purpose of food, but as an unguent for the cure of cutaneous distempers in men and cattle, as well as other complaints, and it is also good for burning. In the surrounding country no other [oil] is used in their lamps, and people come from distant parts to procure it.
[An early Western report of petroleum seepage. He visited the city of Baku, Azerbaijan in 1264.]

Truth and understanding are not such wares as to be monopolized and traded in by tickets and statutes and standards. We must not think to make a staple commodity of all the knowledge in the land, to mark and license it like our broadcloth and our woolpacks.

Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did. So throw off the bowlines, Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.

We are having wool pulled over our eyes if we let ourselves be convinced that scientists, taken as a group, are anything special in the way of brains. They are very ordinary professional men, and all they know is their own trade, just like all other professional men. There are some geniuses among them, just as there are mental giants in any other field of endeavor.

We have taken to the Moon the wealth of this nation,
the vision of its political leaders,
the intelligence of its scientists,
the dedication of its engineers,
the careful craftsmanship of its workers,
and the enthusiastic support of its people.
We have brought back rocks, and I think it is a fair trade . . .
Man has always gone where he has been able to go. It’s that simple.
He will continue pushing back his frontier,
no matter how far it may carry him from his homeland.

When the state is shaken to its foundations by internal or external events, when commerce, industry and all trades shall be at a stand, and perhaps on the brink of ruin; when the property and fortune of all are shaken or changed, and the inhabitants of towns look forward with dread and apprehension to the future, then the agriculturalist holds in his hand the key to the money chest of the rich, and the savings-box of the poor; for political events have not the slightest influence on the natural law, which forces man to take into his system, daily, a certain number of ounces of carbon and nitrogen.
Reflecting on events of 1848.
